Abstract

Voltage stability is very important in electrical systems. The voltage and stability of the system can be significantly impacted by reactive power flows. Static Synchronous Compensator (STATCOM) is one of the converter-based Flexible Alternating Current Transmission Systems (FACTS) devices used for reactive power compensation. In this study, a voltage regulation simulation was carried out via STATCOM in a 400 kV and 2*12 MVAr power system located in Kiziltepe District of Mardin Province, which is a joint project of TUBITAK (The Scientific and Technological Research Council of Turkiye) Marmara Research Center Energy Institute and TEIAS (Turkish Electricity Transmission Corporation) 16th Regional Directorate. The bus voltage from the distribution bus of a power transmission system was controlled by the STATCOM despite the changes in the load. Firstly, the working principle of STATCOM was examined, then STATCOM was installed on the distribution bus of a power transmission system located in Kiziltepe District of Mardin Province and its simulation was performed in the MATLAB program. As a result of the simulation, it was observed that STATCOM keeps the busbar voltage at the desired values, provides fast reactive compensation against load changes and increases the voltage stability of the system.

Özet

Gerilim kararlılığı elektrik sistemlerinde çok önemlidir. Sistemin voltajı ve kararlılığı, reaktif güç akışları tarafından önemli ölçüde etkilenebilir. Statik Senkron Kompansatör (STATCOM), reaktif güç kompanzasyonu için kullanılan dönüştürücü tabanlı Esnek Alternatif Akım İletim Sistemleri (FACTS) cihazlarından biridir. Bu çalışmada, TÜBİTAK Marmara Araştırma Merkezi Enstitüsü ile TEİAŞ 16. Bölge Müdürlüğünün ortak projesi olan, Mardin İli Kızıltepe İlçesi'nde bulunan 400 kV ve 2*12 MVAr gücündeki bir enerji sisteminde STATCOM aracılığıyla gerilim düzenleme simülasyonu gerçekleştirilmiştir. Bir enerji iletim sisteminin dağıtım baralarından gelen bara voltajı, yükteki değişikliklere rağmen STATCOM tarafından kontrol edilmiştir. Öncelikle STATCOM'un çalışma prensibi incelenmiş, ardından STATCOM, Mardin İli Kızıltepe İlçesi'nde bulunan bir enerji iletim sisteminin dağıtım sistemine kurularak MATLAB programında simülasyonu gerçekleştirilmiştir. Simülasyon sonucunda, STATCOM'un bara voltajını istenen değerlerde tuttuğu, yük değişimlerine karşı hızlı reaktif kompanzasyon sağladığı ve sistemin gerilim kararlılığını artırdığı gözlemlenmiştir.
